What the result tells you
This is a capital repayment calculation. Each payment covers interest and some principal. It assumes the same borrowing rate for the whole term, with equal monthly payments and no fees.
The monthly payment is not the whole cost
Compare total repaid alongside the monthly figure. A longer term can reduce the payment while increasing the interest paid. Make a second calculation with a higher interest rate to see how exposed your budget is.
How to use a real offer
Enter the amount actually borrowed and the contractual borrowing rate. APR or APRC may include fees and other assumptions, so it is not interchangeable with the nominal rate used here. Check the lender’s illustration for the actual payment schedule.
Common questions
Does the result mean I can borrow this amount?
No. It does not check affordability, credit history, deposits or lender criteria.
What happens at a zero interest rate?
The amount borrowed is divided equally across the monthly payments.
